Dell XPS 15 7590 BIOS unlock

[gagan]

Of course it's a 3 volt chip

Hi Markus , so its been 24 hours i have changed the chip and flashed the bios that you cleaned for me. There seems to be zero issues. I have disabled UEFI updates as a precaution. Thank you so much for all the help you offered.

Also for anyone else who's having bios auto-recovery issues, you should try replacing the bios chip.

I will keep using the laptop and if there are any issues, i ll post an update here.

Thank you so so much, Markus. You are awesome.

Hello,
I had the same problem once with a Dell 5590.
I also recreated the BIOS with 3 and 6 flashing and then everything worked normally.
Days later the same 3 and 6 flashes again, I then discovered that the Gigadivece IC itself was defective.
Then I used a Winbond and everything was fine.
I would use a new chip or another chip for you.

Hi markus, the bios gives issue on reboots, I flashed the bios again, turned off auto recovery, used it on windows for couple of hours. it rebooted once perfectly fine, but on second reboot , the bios crashed and showed 3 orange 6 white led blinking. I read the bios again and am attaching it here.

Hi, try and feedback

Hi just checking back if possible to fix the keyboard issue, for some reasons even with the somewhat working bios the keyboard keys qwer uiop arent working, even after doing recovery and update using ctrl + esc recovery..

[gagan]

Hi, try and feedback

The laptop boots fine - specific keys still do not work - namely - qweruiop . It autoflashed and updated to 1.27 . i disabled uefi bios updates in bios and flashed your firmware again. Rebooted the laptop and Firmware Update started again and failed and windows turned on, restarted again and firmware update started again(updaing system bios with bios guard), bios updated again and windows loads up, keyboard was working fine before these bios issues, so its not hardware issue . I also tested the keyboard in the bios after i have just flashed the file you provided and the specified keys dont work.

Thanks again for your help

Auto Recovery triggered during boot and didnt properly flash, now top row of keyboard does not work from q to p . Have to fiddle a lot to make it turn on, charger disconnect and reconnect multiple times. Crashes automatically. I have made a new backup of bios. Attached below. Please help.

Thank you

Hello try ....

This message related to the BIOS appears every time the system is started.
The keyboard and touchpad do not work in the BIOS, but they function correctly in the operating system.
